Question about Televison & Video
The scan lines of my sony tv (KV29C5A) are visible on the screen (very faint). Can anyone help me find the source of this problem?
Two possible reasons/solutions why:
1. one or more of your color drive transistors is/are faulty. These are the 3 transistors normally heatsinked in a separate squarish PCB connected at the rear end of the picture tube (CRT). If one or more is shorted, open is leak, then the video display would have faint re-trace lines. other indicators include too bright, unusual color;
2. the screen voltage from the flyback transformer (FBT) is a bit high. This is adjustable and the control is normally at the FBT itself (towards the rear). There is another control present for the focus.
Of course the usual safety precautions applying when working with live sets or electronics with high voltage and possible residual power (in the capacitors).
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
